My teachers never said anything. They just...let the kids be immature. I mean, it was 6th and 7th grade, so the teachers expected us to act like four year olds (lol). But I actually enjoyed it when they were talking about the artwork, and kind of missed it when the picture was gone. I think I got over my immaturity towards nude art in...fifth grade, well, after fifth grade, because my teacher acted like a kid, so he kind of acted grossed out with the pictures.
